Homme \u00abMust Black\u00bb \u2014 t\u00f5eliselt interneti projektide jaoks t\u00e4hendab see, et saidi koormus kasvab m\u00e4rkimisv\u00e4\u00e4rselt. Isegi hiiglased ei pruugi sellega toime tulla, nagu juhtus n\u00e4iteks juhtus<\/a><\/noindex> Amazoniga Prime Day'il 2017. aastal.\u00a0<\/p>\n

\"Elame<\/a><\/noindex><\/p>\n

Oleme otsustanud tuua m\u00f5ned lihtsad n\u00e4ited virtuaalserveriga t\u00f6\u00f6tamisest, et v\u00e4ltida vigu ja mitte kohtuda rahvaga 503 lehega v\u00f5i mis veel hullem, About:blank ja ERR_CONNECTION_TIMED_OUT. J\u00e4\u00e4nud on \u00fcks p\u00e4ev, et valmistuda.
\n<\/a><\/noindex><\/p>\n

Ressursside skaleerimine<\/h2>\n

\nSait koosneb tavaliselt erinevatest moodulitest \u2014 andmebaas, veebiserver, vahem\u00e4lu s\u00fcsteem. Iga\u00fchel neist moodulitest on erinevad ressursi vajadused ja mahud. Tuleb eelnevalt anal\u00fc\u00fcsida tarbitavate ressursside hulka stressitestide abil ja hinnata ketta sisend-v\u00e4ljundi kiirus, protsessorite aeg, m\u00e4lu ja teie saidi interneti ribalaius.<\/p>\n

Stressitestid aitavad tuvastada teie s\u00fcsteemi kitsaskohti ja neid eelnevalt skaleerida. N\u00e4iteks v\u00f5ite suurendada teie serveri v\u00f5imsust, suurendades k\u00f5vaketta mahtu kampaania ajaks, laiendada saidi ribalaiust v\u00f5i suurendada virtuaalse serveri RAM-i. P\u00e4rast kampaaniat saab k\u00f5ik tagasi muuta, seda tehakse kasutajaprofiilis ilma tehnilise toe poole p\u00f6\u00f6rdumiseta ja see v\u00f5tab paar minutit, kuid parem on seda teha eelnevalt ja madala klienditegevuse ajal saidil.<\/p>\n

Kaitske end eelnevalt DDoS-r\u00fcnnakute eest<\/h2>\n

\nKampaaniap\u00e4evadel kukuvad saidid mitte ainult klientide voolu kasvu t\u00f5ttu, vaid ka DDoS-r\u00fcnnakute t\u00f5ttu. Need v\u00f5ivad olla korraldatud pahatahtlike isikute poolt, kes soovivad suunata teie liiklust oma petusaitidele.\u00a0<\/p>\n

DDoS-r\u00fcnnakud muutuvad iga p\u00e4ev \u00fcha keerukamaks. H\u00e4kkerid kasutavad erinevaid l\u00e4henemisviise, rakendades samaaegselt DDoS-r\u00fcnnakuid ja rakenduste haavatavuste r\u00fcnnakuid. Enamikul juhtudel kaasnevad r\u00fcnnakutega katsetused saidi h\u00e4kkimiseks.<\/p>\n

Siin on samuti oluline eelnevalt valmistuda ja \u00fchenduda teie serverisse r\u00fcnnakute eest kaitstud IP-aadressiga. UltraVDS-is kaitseme servereid mitte ainult r\u00fcnnaku toimumisel, vaid pidevalt ja suudame stabiilselt taluda r\u00fcnnakuid kuni 1,5 Tbps! DDoS-r\u00fcnnakute kaitsmiseks kasutatakse filtrite seeriat, mis on \u00fchendatud interneti\u00fchendusega, millel on piisavalt suur l\u00e4bilaskev\u00f5ime. Filter anal\u00fc\u00fcsib j\u00e4rjestikku l\u00e4bivat liiklust, tuvastades k\u00f5rvalekalded ja ebatavalise v\u00f5rguaktiivsuse. Anal\u00fc\u00fcsitavate ebatavalise liikluse mustrite hulka kuuluvad k\u00f5ik t\u00e4nap\u00e4eval tuntud r\u00fcnnakute meetodid, sealhulgas need, mida viiakse l\u00e4bi jaotatud robotiv\u00f5rkude abil.<\/p>\n

\u00dchendamiseks kaitstud aadressiga virtuaalserverisse tuleb saata taotlus teenusepakkuja tugiteenusele eelnevalt.<\/p>\n

Selleks et kiirendada saidi laadimist<\/h2>\n

\nKampaaniate ajal suureneb serverite koormus, saidid hakkavad aeglaselt laadima pilte ja toote kaarte. Lehek\u00fclgede laadimist raskendavad ka erinevad raamistikud, JS-raamatukogud, CSS-moodulid jne. Potentsiaalne klient v\u00f5ib lehelt lahkuda, saamata vastust saidilt, isegi juhul, kui pakkumine on soodsam kui konkurentidel. Lehek\u00fclgede laadimise kiiruset\u00f5stmiseks soovitame kasutada Google DevTools'i.<\/p>\n

Saidiga lehek\u00fclgede laadimise kiiruset\u00f5stmiseks aitab ka sisuteenuste v\u00f5rk (Content Delivery Network, CDN). CDN on geograafiliselt hajutatud v\u00f5rk, mis koosneb vahem\u00e4lupunktidest - kohaloleku punktidest, mis v\u00f5ivad asuda kogu maailmas. Kui klient k\u00fclastab saiti, saab ta staatilise sisu mitte teie serverist, vaid CDN-v\u00f5rku kuuluvast serverist, mis asub temale l\u00e4hemal. T\u00e4nu marsruudi l\u00fchendamisele serveri ja kliendi vahel laaditakse saidi andmed kiiremini.<\/p>\n

CDN-v\u00f5rku v\u00f5ib seadistada ise, kui teil on VDS Windows Server Core 2019, kasutades selleks operatsioonis\u00fcsteemi sisseehitatud t\u00f6\u00f6riistu nagu: Active Directory, DFS, IIS, WinAcme, RSAT. Samuti v\u00f5ib kasutada valmis lahendusi, n\u00e4iteks Cloudflare'i CDN, mis v\u00f5iks probleemi lahendada oluliselt kiiremini ja odavamalt. Lisaks on sellel s\u00fcsteemil ka lisav\u00f5imalused: DNS, HTML, CSS, JS tihendamine, palju kohaloleku punkte.<\/p>\n

Edukaid m\u00fc\u00fcke.<\/p>\n

Must reede UltraVDS-is<\/h2>\n

\nMe ei j\u00e4\u00e4nud ka vahele traditsiooniliste allahindluste pakkumisest sel p\u00e4eval ning pakume Habr'i kasutajatele sooduskoodi BlackFr<\/b> 15% allahindlusega meie k\u00f5igi virtuaalserverite peale alates 28. novembrist kuni 2. detsembrini kaasa arvatud.<\/p>\n

N\u00e4iteks, VDS<\/a><\/noindex> UltraLight plaani server 1 CPU tuumaga, 500 MB RAM-i ja 10 GB kettaruumiga, mis t\u00f6\u00f6tab Windows Server Core 2019 all, saab osta sooduskoodiga BlackFr<\/b> lisaks 30% allahindlust aastas vaid 55 rubla kuus, seega on kogusoodustus 45% praegusest hinnast.<\/p>\n
